LUBRICATING IIIIFIAIS.l

Application led August 8, 1921. Serial No. 490,491.

T 0 all whom z't may concern:

Be it known that I, DOUGLAS F. FE'sLnR, a citizen of the United States,and resident of Evanston, in .the county of Cook .and

State` of-Illinois,..'have invented a certain new and useful Improvementin Lubricating Means, of which the following is a ful,

Iclear, concise, and exact description, reference being had to theaccompanying drawin s, forming a part of this speci cation. inventlonrelates to improvementsv in lubricating means, and is particularlyconcerned with the provision of novel means for expediting andfacilitating the filling of lubricant compressors, grease cups, etc.

The objects of my invention are- First: To provide a novel type ofcontainer orcartridge for holding a charge of lubricant to be insertedin a lubricant com- 26 pressor or grease cup, the said cartridgecomprising'means for displacing the contents therefrom;

Second: To provide a container of the character described which can beeasily and 25 quickly connected with the open end of a lubricantcompressor or grease eu so that the contents of the container cantransferred to the compressor or grease cup without loss of any of thecontents, and without soiling the hands of the operator;

Third: To provide a container of the character described which is simplein constrlction, and economical to manufacture, an

Fourth: To provide a novel lubricant package which can be transportedwithout danger of loss of the contents thereof, and which can bemanipulated to easily and quickly fill the barrel of the lubricantcompresser or grease cups.

Other objects will appear as this description progresses, referencebeing had to the accompanying drawings in which- Figure 1 1s a sideelevation of my improved grease cartridge.

Figure 2 is a central longitudinal section;

Figure 3 is an end view showing one of the end closures removed, and,

Figure 4 is a view partially in longitudinal section, showing the methodof using my improved cartridge` for-filling the barrel of a grease gun.

Throughout the several views similar reference characters will be usedor referring to similar parts.

My improved cartrid e or lubricating' to the internal diameter of thebarrel ofthe lubricant compressor or other receptacle to which thelubricant from the container 5 is to be transferred. The cap 9,'

made preferably from the same material as the tubes 6 and 7, closes theend of the container having the projecting end portion 8 of reduceddiameter, and a similar cap 10, but of slightl large diameter, closesthe opposite end of the container.

I prefer to impregnate the material formingil the container andthe twocaps with so 'um silicate or any other suitable lubricant repellingmaterial seas to-prevent the lubricant from escapin through the pores ofthe material from w ich the container is formed.

Adjacent the end closure 10 of the container, and slidable within thecontainer, I provide a plunger 11 comprising a disk portion having acentral inwardly extending depression 12, and an outwardly extendingperipheral flange 13. Preferably, this plunger is made of sheet iron,tin, or other similar material. l

The, method ofy filling a lubricant compresser or other lubricantreceptacle with lubricant by the use of my im roved lubricating means isillustrated in Figure 4l For this purpose, the cap 9 is first removedfrom the end of the container, and Ithe portion 8 of reduced diameter isinserted in the end of the compressor, as shown in Figure 4. yA screwdriver, pencil, or any other suitable tool is then forced through thefrangible closure 10, and forced downward against the plunger 11. Theconical shaped central depression 12 causes the instrument thus used toseek the center of the plunger 11, and

thus prevents the plunger from tipping when continued pressure isapplied to the instrument to force the plunger toward the com ressorbarrel for the purpose of transferrlng the contents of the container 5from the container to the barrel of the com-v presser.

The ange 13 also tends to prevent the plunger from tipping in thecontainer, and the closure 10 prevents the dislodgment of the plunger 11from the container during shipment.

While it is possible to make the container 5 of sheet metal, or othermore or less rigid material, I prefer to make it of the materialspecified, or other similar materials, because if, during shipment,depressions should be formed in the side walls of the container, theyare easily forced outward by the plunger 11 by its passage through thecontainer so that they will not prevent the discharge of the entirecontents of the container.

While I have described the details of construction of the preferredembodiment of my invention, it is to be clearly understood that myinvention is not to be limited to these details, but is capable of otheradaptations and modifications within the scope of the appended claims.

Having thus described my invention, what I claim is:

1. A packa comprising a cylindrical container fille with lubricant, thesaid container being made of brous material and 'having a removableclosure at one end, a frangible closure at the other end, and a plungerslidable in said container, the said plunger having an outwardlyextending Hange and a central inwardly extending depression.

2. A container filled with lubricant; the said container being made ofibrqus material and having a removable closure at one end, a frangibleclosure at the other end, and a plunger slidable in said container, thesaid plunger having an outwardly extending flange.

3. A package comprising a cylindrical container filled with lubricant',the said container being made of ibrous material and having a removableclosure at one end, a frangible closure at the 'other end, and a plungerslidable in said container, the said plun er having a central inwardlyextending epression. j

4. A package comprising a cylindrical container filled with lubricant,the said container being made of fibrous material and having a removableclgsure at one end, a frangible closure at the other end, and a plungerslidable 'in said container.

In witness wheref, I hereunto subscribe my name this 4th day of August,1921.
